SPECIFICATION forming part of Letters Patent No. 617,127, dated January 3, 1899.

Application filed April 6, 1898. Serial No. 676,674. (No model.)

To ctZZ whom, it may concern.-

Be it known that I, OAMILLO SAVINO, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Syringes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention, as will be hereinafter fully described and claimed, relates to syringes, and more particularly to that variety thereof wherein dependence is had upon a collapsible or flexible body to discharge the contents thereof.

The object of my invention, among others, is to provide a reliably eflicient syringe, into which the contents to be discharged therefrom may be easily and quickly introduced and thoroughly protected from any impurities or foreign substances while so disposed.

A further object is to provide means of simple construction which will retain the contents within the body of the syringe until it is desired to use the same and permit such discharge to be made in any desired quantities, thus obviating the necessity of providing valves of a special and expensive construction.

A further object is to provide a resilient mouthpiece or nozzle which will be soft and grateful to the touch, enabling the syringe to be applied to the nose, ear, or other delicate organs without fear of injury resulting therefrom.

In the accompanying drawings, Figure 1 is a side elevation of my syringe complete,showing the sealing-cap removed therefrom. Fig. 2 is a central longitudinal section of my improved syringe and cap. Fig. 3 is a detail in side elevation, showing the rigid throat removed, the scale being slightly enlarged from that shown in Fig. 2. Fig. 4 is a detail showing a modified form of construction for the rigid throat.

Briefly stated, my invention consists in a flexible body-section, preferably bulbous in form, a flexible nozzle and a rigid throat de signed to connect said body and nozzle, said throat having a threaded section located,preferably, near its central part, designed to promy invention, 1 represents the body of my syringe, which may be made to have any suitable or preferred outline and is preferably provided with a base-section 2, which provides a bottom, upon which said body may rest in an upright position. The upper end of the bulbous body thus provided is designed to receive the lower end of the rigid throat, which consists of the anchoring-stems 3 and the enlarged centrally-disposed and exteriorly-threaded section 4:, designed to receive the lower internal rim of the sealing-cap or cover 5. The upper and lower stem 3 may be constructed substantially as shown in Figs. 2 and 3 or as illustrated in Fig. 4:, the office thereof being to provide means for holding the flexible body 1 and the nozzle-section 6 in union with each other. Said nozzle-section 6 and the body-section 1 are preferably formed of soft rubber, though any suitable material may be employed, the object being to provide means which will enable a vacuum to be created by compressing said body, which will result in filling said body with any desired liquid or other contents when the pressure is removed.

The nozzle-section 6 consists of a flexible sack-like body,which may be readily stretched over the anchoring-stem 3, and since said stem is provided at its extreme end with an annular rib 7 both the flexible body and the nozzle will be held in position thereon, the free edges of each abutting against the shoulders 8 of the enlarged threaded portion 4.

The nozzle-section 6 terminates in the flexible nipple 9, provided with a small bore or aperture, through which the contents may be forced by compressing a flexible body, and in order to prevent the contents from escaping through such aperture I provide the sealing-cap or thimble 5, which is provided in its extreme inner end with a tapering bore or conical seat 10, designed to snugly receive said nipple and compress the extreme point thereof sufficiently to close the aperture therein, and thus effectually prevent casual dis charge of the contents.

The lower edge of the thimble or sealingcap 5 is interiorly threaded to cooperate with the threaded body-section 4, and it will be readily apparent that when said cap is turned home upon said body the contents Will be securely held in position until said cap is removed.

In Fig. 4 I have shown another form of construction for the surface of the stems 8, consisting in providing a series of ribs 11v so formed that inclined faces will be presented and disposed in such a Way that each rib will in cross-sections represent the base of a cone, the base-line thereof being disposed nearest the enlarged threaded body-section 4E, and thus provide means which will effectually hold the flexible end of the body or nozzle sections in position when forced thereon, as will be readily apparent.

The numeral 12, as will be seen by reference to Fig. 4 of the drawings, shows the ribs 11 disposed spirally, said ribs being triangular in cross-section and having the appearance of a ratchet-tooth, as the outer wall of the rib is inclined, while the inner wall is vertical or at right angles to the plane of the body, and it is obvious that such construction will readily permit the flexible body or the nozzle to be slipped over the same and that a reverse movement of said parts will be much more difficult. These lips may be annularly or spirally formed, and if spirally formed a few rotations of the flexible part or the rigid throat will bring all of said parts into close relationship with each other.

In placing the end 11 in position all that is necessary is to simply force the same into the mouth of the body or nozzle section, while the introduction of the opposite end wherein the ribs are shown spirally disposed may be accomplished by a few simple rotations of the bod y-section 4.

It will be understood that the body-section and anchoring-stems may be made of suitable material which will give the desired rigidity, as hard rubber, celluloid, or the like. A suitable bore 13 is provided throughout the body-section and stems thereon, through which the contents of thebody 1 may be discharged, the freedom of discharge being controlled by the size of the aperture provided in the nipple 9.

lVhile I have described the preferred accessories deemed necessary in providing a complete syringe of the character specified, it will be understood that I desire to comprehend the substantial equivalent thereof, and I do not therefore wish to be confined strictly to the axact showing I have made.

It is thought that my syringe will be desirable for all the purposes for whichasyringe of this character is adapted and will in addition be found valuable and efficient for use as a medicine-bottle, wherein it is desired to preserve against the time of use in form of liquid or even powdered contents. It will also be clear that my syringe, consisting, as it does, of but four separate simple parts, may be readily disassembled for the purpose of cleansing, sterilizing, 850., or for replacing any one of such parts found deficient. The contents may be readily introduced by simply withdrawing the anchoring-stem 3 therefrom.

My syringe may be made any preferred size, and when made of substantially the size shown in the drawings it will be found very desirable for pocket use, thus enabling the user to safely carry his medicine about with him.

Having thus fully described myinvention, What I claim as new, and desire to secure by Letters Patent, is

1. The herein-described syringe consisting of the body, a flexible tapering nozzle having a discharge-aperture, a neck having an exteriorly-threaded middle section and reduced end sections designed to connect said body and nozzle, and a thimble or cap fitting over said flexible nozzle-section and engaging said exteriorly-threaded portion and further provided with a centrally-disposed tapering seat or bore designed to receive said tapered end of the flexible nozzle as and for the purpose set forth.

2. As an article of manufacture, thehereindescribed syringe consisting of a flexible body, a flexible nozzle having a tapering dischargenipple, a tubular section having an enlarged middle portion provided with exterior threads and further provided with threaded end portions, a thimble or cap having internal threads designed to be received by the threads upon said middle portion as specified and for the purpose set forth.

3. As an improvement in syringes, the combination of a tubular neck portion having an enlarged exteriorly-threaded middle section and anchoring-stems or end sections; a bulbous body-section; a flexible nozzle-section; a cap provided with a seat for the point of said nozzle, and an interiorly-threaded rim, and means carried by said stems or end sections for engaging said body and nozzle and thus holding them in operative union with each Other, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

OAMILLO SAVINO.
